And the patent contained the following:
The inventive pyrazole ketone compound has structure shown as general formula I, wherein R1R2N represents (un)substituted 3-8 membered nitrogen-containing heterocyclic group containing 1-3 hetero atoms, or R1 and R2 are independently H, alkyl, heteroalkyl, etc.; R3 is H, alkyl, alkenyl, alkynyl, cycloalkyl or alkyl substituted cycloalkyl; R4 is Me, Et, Pr, iso-Pr, or cyclopropyl; X is H, S(O)nR6, R7, or (substituted) 3-8 membered heterocyclic group containing 1-4 hetero atoms, n is 1, 2 or 3; R6 is (un)substituted alkyl or aryl, R7 is (un)substituted alkyl, aryl, alkanoyl or aroyl. Compounds of the invention were prepared and evaluated for their herbicidal activity on various crops (data given). The pyrazole ketone compound has good herbicidal effect, convenient application, low cost, and high com. value. The experimental process involved the reaction of 5-Methoxy-1H-pyrazole(cas: 215610-30-3).Computed Properties of 215610-30-3
